Checkmate

What this skill does

Enforces task completion: turns your goal into pass/fail criteria, runs a worker, judges the output, feeds back what's missing.

Checkmate is part of the Automation & Workflows category — automation and workflow skills that schedule, trigger, and orchestrate tasks. You can install it on its own or alongside other automation & workflows skills from the OpenClaw catalog.

How to install Checkmate

The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:

1. Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
2. Open the in-app Skills panel.
3. Search for checkmate and click Install.
4. The skill activates automatically when an incoming message matches its description.

Install from the command line

If you already run the OpenClaw CLI, add Checkmate with a single command:

openclaw skills add checkmate

This pulls checkmate from ClawHub and installs it into ~/.openclaw/skills/checkmate/. Restart the OpenClaw gateway afterwards so the new skill is discovered.

How to use Checkmate

Once installed, Checkmate activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.

Manual install (advanced)

If you prefer manual installation:

1. Click the Download .zip button above to grab checkmate-2.0.4.zip directly from our S3 mirror.
2. Unzip into ~/.openclaw/skills/checkmate/ (create the directory if it does not exist).
3. Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
